SUMMARYFarmer participatory varietal selection (PVS) was used to identify farmer-acceptable cultivars of rice and chickpea. Farmers' requirements in new crop cultivars (varieties) were determined, a search was carried out for released and non-released cultivars that matched these needs, and they were tested in farmer-managed, participatory trials. Farmer-acceptable cultivars were found amongst released material, but not among the recommended material for the area. Lack of adoption is, therefore, because resource-poor farmers have not been recommended or exposed to the most appropriate cultivars under the existing system of varietal identification and popularization. Adoption rates of cultivars would be improved by increased farmer participation, the systematic testing in zonal trials of locally popular cultivars to define their domains properly, a more liberal release system, and a more open system of providing seeds of new cultivars to farmers.

SUMMARYA participatory plant breeding (PPB) programme was conducted for the high altitude areas of Nepal. The aim was to breed acceptable varieties with minimum use of resources and to utilize farmers' knowledge in the PPB programme. Farmer participation began at the F5 stage and progress was followed over two seasons in two villages. Farmers proved to be willing participants and made selections in the segregating material, often with great success. Large differences in farmers' preferences between the F5 bulks were found and the most preferred were adopted rapidly. The most adopted variety, Machhapuchhre-3, performed well in the formal trials system, and much better than the products from conventional centralized breeding. The PPB programme increased biodiversity in the two participating villages.

Participatory varietal selection in a development project in western India showed that the rice (Oryza sativa) variety Kalinga III was highly preferred by farmers. The spatial diffusion of this variety from three villages (two project and one non-project) was studied. Seed of Kalinga III had spread from the three villages in 1994 to 41 villages by 1996 and is estimated to have reached over 100 widely distributed villages by 1997. Farmer-to-farmer spread was as high from the non-project case study village that received no further seed from the project, possibly because farmers are more likely to spread seed of a new variety to other farmers when they have no assured supply. Project interventions used key villages, informal-sector seed merchants, and Non-Government Organizations in the spread of seed. The project also collaborated with Rajasthan State Agricultural University and Kalinga III has been proposed for release in that state. A financial analysis revealed the very high internal rates of return that are possible from investment in participatory varietal selection.

Participatory Crop Improvement

A field study was undertaken on Nepalese fingermillet genotypes with the participation of the local community at pipaltar of nuwakot district during 2003 and 2004. The study included a) identification of superior fingermillet cultivars through diversity block management and mother set trial, b) seed Production of promising lines, c) farmers' field verification trial (diamond trial) And d) characterization and documentation of fingermillet genotypes. Results Revealed that mudke, chaure and jalbire are high yielding promising genotypes Suited to that area. From household surveys carried out among 46 samples (40%), 80 hh have revealed that mudke, chaure and seto kodo are preferred fingermillet cultivars. About 70% grow mudke, 46% grow chaure while 2% Grow Seto Kodo. The programme has successfully explored the potential of Local fingermillet cultivars by there evaluation and utilized them through Value added product development and market promotion. Nepal Agric.

SUMMARYSoyabean (Glycine max) is a relatively new crop for small-scale farmers in Zambia which has been adopted following the introduction of new cultivars, greater opportunity to obtain credit, easier marketing and an attractive guaranteed price. However, low yields limit production partly due to the lack of a planting method that establishes optimal populations. The present method is to plough and plant in the same operation, dribbling the seed behind the ox-plough. This often leads to uneven depth of planting, and hence to poor seedling emergence and erratic stands. Alternative planting techniques evaluated on farmers' fields for three seasons (1985/86–1987/88) suggest that farmers should replace their practice of planting behind the plough with either hand seeding following a plough–harrow operation or the use of a modified ox-drawn planter (Taparia).

E-Services have great potential, even in resource-poor environments such as in sub-Saharan Africa. However, contextual factors pose significant challenges for development, feasibility, deployment and sustainability of e-services. This chapter presents a case of e-service value co-creation in a rural context, with targeted end users in regions characterized by limited electricity infrastructure and poor or absent internet, strong diversity in languages spoken, high illiteracy rates and limited purchasing power. It offers a methodology to upfront analyze business model sustainability for e-service innovation in severely resource-constrained contexts. This is illustrated by an extensive case study in which a voice-based microblogging e-service was developed and deployed with local stakeholders in rural Mali.
